High school loner to cold-blooded executioner

(London Daily Mail) A troubled 20-year-old loner with a history of autistic behavior is the monster behind a horrific shooting at a Connecticut elementary school that left 26 people, including 20 children, dead on Friday.

Adam Lanza shot his mother, Nancy, at the upscale suburban home they shared together and then took three of her guns and drove to Sandy Hook Elementary School about 9.30am.

He used two semi-automatic pistols, a Glock and Sig Sauer, and reportedly wiped out an entire classroom of young children, then shot several in a second class before taking his own life.

Witnesses say Lanza was going from room to room shooting people, after first killing the principal Dawn Hochsprung and the school psychologist Mary Sherlach execution-style when they confronted him in the hallway.
